AC/DC Off-Line Switcher IC, TOPSwitch-HX, Flyback, 85 VAC - 265 VAC, 66 kHz,11.1 A out, 333W, SIP-7Product OverviewTOPSwitch-HX family enhanced EcoSmart, integrated off-line switcher withadvanced feature set and extended power range. TOPSwitch-HX cost effectivelyincorporates 700V power MOSFET, high voltage switched current source, PWMcontrol, oscillator, thermal shutdown circuit, fault protection and othercontrol circuitry onto a monolithic device. It is a highly integrated monolithicoff-line switcher IC designed for off-line power supplies. TOPSwitch-HXintegrated circuits enable design of power supplies up to 195W, while providinghigh efficiency under all load conditions. Also provides very good performanceat low load and during standby (no load) operation. TOPSwitch-HX allows designerto meet efficiency requirements for new energy efficiency standards.Applications includes LCD monitor, personal computers, small servers, laptopadapters, set-top boxes, digital TVs, printers, DVD players and recorders, UPS,video games, broadband modems, cellular phone adapters and audio amplifiers.177W (adapter), 333W (openframe) at 230VAC and 118W (adapter), 254W (openframe)at 85-265V O/P powerMulti-mode operation maximizes efficiency at all loads, EcoSmart- energyefficientExtended creepage between DRAIN and all other pins improves field reliabilityFrequency jittering reduces EMI filter cost, allows both primary and secondarysensingLine undervoltage (UV) detection prevents turn-off glitchesLine overvoltage (OV) shutdown extends line surge limitAccurate programmable current limit, optimized line feed-forward for line ripplerejection132KHz frequency (254Y-258Y and all E/L packages) reduces transformer and powersupply sizeHalf frequency option for video application, fully integrated soft-start forminimum start-up stressOutput OVP is user programmable for latching/non-latching shutdown with fast ACresetProduct InformationInput Voltage AC Min: 85VInput Voltage AC Max: 265VAC / DC Converter Case Style: SIPNo. of Pins: 7PinsPower Rating: 333WTopology: FlybackOperating Temperature Min: -40°COperating Temperature Max: 150°CProduct Range: TOPSwitch-HX Series
